Flood Watch

Redondo Beach, WA

Day 1: May 22, 2025

CATEGORY 1

WHAT
No risk of flooding. Tides will rise to around 19.4 ft during peak times, but barometric pressures remain relatively high (above 1014 hPa), and NOAA predicts a 0.0% flood likelihood.

WHEN
Highest tides around 00:18 and 12:48 (local times).

IMPACTS
No anticipated coastal inundation or flood-related property impacts.

ADDITIONAL DETAILS...

• Barometric pressure readings are not near the historically significant low-pressure thresholds (<992.8 hPa) that have contributed to flooding in the past.
• Compared to historical Category 3, 4, and 5 events, both the tidal heights and atmospheric pressures indicate minimal risk.
• NOAA CO-OPS Flood Likelihood remains at 0.0%, reinforcing no expected flooding conditions for this period.


Day 2: May 23, 2025

CATEGORY 1

WHAT
No risk of flooding. While high tides approach 19.4–19.5 ft, pressures remain above 1014 hPa and NOAA flood likelihood is 0.0%.

WHEN
Highest tides around 00:54 and mid-afternoon (14:06).

IMPACTS
No flooding is anticipated; all coastal areas should remain clear of water intrusion.

ADDITIONAL DETAILS...

• Even though the tide is moderately high, it does not come close to the >21 ft heights observed in past flooding events.
• Wind speeds are light (generally below 10 mph), and wind direction is not forecast from the critical W/NW direction at intensities known to push water ashore.
• Historical events in the Category 3–5 range involved significantly lower barometric pressures or higher tides than those predicted for today.


Day 3: May 24, 2025

CATEGORY 1

WHAT
No risk of flooding. Tides may briefly near 19.7 ft in the early morning, yet barometric pressure (about 1011.8 hPa) remains well above threshold levels that historically correlate with flood risk. NOAA’s daily flood likelihood is still 0.0%.

WHEN
Highest tides around mid-morning (10:36) and mid-afternoon (15:18).

IMPACTS
No threat to coastal infrastructure or property is expected.

ADDITIONAL DETAILS...

• Despite being slightly lower in pressure than Days 1 and 2, the barometric pressure is still far from critically low.
• Tidal heights remain under the ~21 ft benchmark often associated with more serious flood events.
• No notable storm surge or strong onshore winds are predicted; historically, these factors have usually amplified flood risks.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

CATEGORY KEY

• Categories 1-2: No risk of flooding.
• Category 3: Close to a flood event and worth monitoring.
• Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
• Category 5: Likely to flood and cause property damage.
• Categories 6-7: Extremely high risk of flooding and property damage.
